,ment represented into the path of the liquid discharged from the receptacle upwardly through the open end of the pipe 13, for deflecting the liquid downwardly against material hereinafter referred to positioned in the receptacle 20, these means as shown being in the form Vof an inverted dished member 24 secured to the yoke 21 in the aperture 22 thereof to extend directly above the bore 23 in the Vyoke and concentrically thereof, asa screw' 25l screwing l and which closely fits in the outwardly flar bore 23, and a fusible eleat 29 and formed, as forexample of a bar section 30 ofV brass confined in the slot 31 of the screw 25, and a section 32 connected with the section 30 in alinement therewith and engaging a slot 33 in the upper end of the plug 27 the section 32being of any desirable material which fuses at the temperature at which it is desired the fire-extinguisher.automatically operate, such for example as the material com monly used inthe fusible plugs of automatic fire-sprinkler systems.

,i In conditioning the apparatus for use the liquid to be used, as for example water or water containing chemicals if desired, may

ing mouth of the `be introduced into the receptacle 4 'through lthe filler opening 9, as for example to the height indicated by the line 34, and the receptacle then charged with compressed gaseous material, as, and by, preference, compressed air, to build up a relatively high pressure in the upper part of the receptacle, and any suitable chemical, preferably in solid form, and more preferably molded into a solid mass, and represented at 35 and of such character that when mixed with the liquid used, as forV example water, will operate to aid in 'extinguishing the lire, as by a smothering action, charged into the receptacle 20.

The operation of the apparatus'is asifollows: lVhen the temperatureof the air surrounding the apparatus reaches a degree sufficient to fuse the metal of the section 32, the plug 27 is thereby released permitceptacle 4 to force the liquid therefrom out through the pipe .13 from which it discharges against the Vdeflector 24 which throws the liquid downwardly in all direcy l/Vhat I claim as new and desire to secure by Letters Patent is: V

1. In fire-extinguishing apparatus, Y the 'combination of a vpassage throughv which liquid is discharged, 'a receptacle for a material to become mixed with theliquid, arranged to extend aboutsaid passage,` and a dished deflectorextendingin inverted condition over said passage and positioned-to deflect the liquidV discharging from said pas# sage, downwardly against the material in said receptacle.`

2. In {ireextinguishing apparatus, the combination of a passage through which liquid isdischarged, a receptacle for a material to become mixed with the liquid, fusible means sealing the discharge end ofV said passage, and means for deflecting` the liquid discharging from Vsaid passage, lagainst the material in said receptacle.

ting the compressed. air contained in the re- 3. In a fire-extinguisher, the combination of a receptacle for-liquid, a pipe communieating with the lower end of said receptacle and leading upwardly along thefside of said receptacle and extending upwardly therefrom at a point substantiallycentrally of said receptacle, and a brace for saidpipe connected with saidreceptacle and with said pipe adjacent the center of said receptacle.

4. Ina fire extinguisher, thecombination ofa tank for water containing a compressed fluid and having an outlet, afusible plug restraining the discharge of the water from `said tank, and` av receptacle exterior of said tank 'for causing a vmaterial which when mixed with water operates to smotherffire, to become mixed with thewater in theV flow thereof fromsaid tank.
